In situ loading amorphous CoSx on N-doped g-C3N4 through light assisted synthesis for enhanced photocatalytic hydrogen generation

Loading co-catalysts are an effective strategy to break the confinement of bulk carbon nitride in photocatalysis. Employing this strategy, N-doped g-C3N4 decorated with CoSx was successfully prepared through a photochemical synthesis route. The optimum hydrogen evolution performance of N-CN-CoSx-4 was 1757 μmol g−1 h−1 under visible light irradiation. Superior interfacial carrier transfer properties and improved light absorption of N-CN-CoSx-4 could elucidate its better photocatalytic activity. This research offers a reference for the construction of high-efficiency, stable and low-priced photocatalysts.
